This document helps the user understand the metastable performance of TLI clocked FIFOs in asynchronous-system applications. A basic discussion of metastable-operation theory the equations to calculate metastable failure rates for 1- and 2-stage synchronization and an approach used for synchronizing the state flags on a series of TI clocked FIFOs is provided. A test setup to measure the failure

The initialization of the DDR3 DRAM controller on KeyStone I DSPs is straightforward as long as the proper steps are followed. However, if some steps are omitted or if some sequence-sensitive steps ar

The 3650 is an optically coupled differential input isolation amplifier having programmable gain. Noise for the 3650 is specified to 4u Vrms (typ) on the input stage of the isolation barrier and 65u Vrms (typ) on the output stage. The gain of the 3650 is controlled using exernal resistors on the input stage. In low gains the noise performance of the 3650 is dominated by the output stage noise f

Designing with the DRV421: Closed Loop Current Sensor Specifications DRV421

The UCC39421 SEPIC demo board implements a complete 330-kHz, 3.3-V SEPIC converter. The user needs only to supply an input voltage and a load. A list of materials giving the component part numbers and

Current-feedback amplifiers have ideal closed-loop gain equations identical to voltage-feedback amplifiers but the similarity ends there. The detailed gain equations for the current feedback amplifer are developed here for the inverting and noninverting circuits. This paper goes beyond the gain analysis as it develops the stability criteria and discusses compensation.

The software demonstrates the MPEG-2 high-definition (HD) decoder running on the DM642 Evaluation Module (EVM). The demonstration uses the MPEG-2 HD decoder to decode the MPEG-2 HD bitstream and display the decoded frames on the HD output device.

The demonstration uses:

• MPEG-2 decoder library optimized for a DM642 EVM
• MPEG-2 decoder library implemented using XDAIS interfaces
• Samp

This reference design is presented to help application designers and others who are trying to use the MSP430 in a system with an input voltage in the range of 3.6 V to 5.5 V and who are also intereste

Two generations of powered device (PD) controllers are available from Texas Instruments for Power-over-Ethernet PD solutions. They are the TPS2370/TPS2371 and the TPS2375/TPS2377. While they are largely pin-compatible some differences between these two families of PD controllers make the TPS2375 and TPS2377 the preferred devices. This report explains the major differences between the two families

Microcontroller units (MCUs) are generally limited with lower drive on the I/Os. Most of the applicationsrequiring MCU boards to drive high-current loads need discrete implementation and additional components which use a lot of board space. This board space is called a peripheral driver section. The TPL7407L device is an integrated peripheral driver with seven channel drivers inside. The TPL740

Systems engineers must apply real-time digital hardware solutions to signal processing problems to achieve the goals of reliability repeatability and flexibility. DSP offers the only such solution for many applications. Digital filter components are an integral part of many DSP systems. In particular continuously programmable digital filters (CPDFs) offer a broad range of high-tech applicatio

The TMS320C6000? on-chip direct memory access (DMA) controller from Texas Instruments is used to transfer data between two locations in the memory map in the background of CPU operation. Typically the DMA is used to:

Transfer blocks of data between external and internal data memories

Restructure portions of internal data memory

Continually service a peripheral

The TPIC6595 is a monolithic device that contains eight 1.5A/45-V low-side DMOS power switches combined with the logic functions of an SN74HC595 and packaged in a 20-pin dual in-line plastic package (DIP) or wide body surface-mount package (DW). The TPIC6595?s outputs are inverted relative to those of the SN74HC595. This document provides a functional description of the TPIC6595 and detailed app

This application note describes how to realize an Electrical Echo Canceller using the LMS instruction of the TMS320LC54x series DSP. Thanks to this compact instruction it is possible to perform the Prediction Filter (FIR) and the weight updating at the same time. The software described is based on the Leaky Normalized Least Mean Square adaptive (LNLMS) filter with single precision (16 bit) coeff
